Abstract
PURPOSE OF REVIEW: Electronic cigarettes (e-cigarettes) are gaining rapid popularity among all age groups, especially among youth. They have evolved into technologically advanced devices capable of delivering nicotine concentration and other substances. In addition to nicotine, e-cigarettes' constituents possess variety of toxic chemicals that have adverse effects on human body. RECENT FINDINGS: In recent years, steady downward trend in tobacco usage has been observed; however, e-cigarette use is on upward trend. E-cigarettes are advertised as "safer" alternatives to conventional smoking and as an aid to smoking cessation. Emerging studies have, however, shown that e-cigarettes have harmful effects on the cardiovascular system and that most of the e-cigarette users are dual users, concurrently using e-cigarettes and smoking conventional cigarettes. Despite a gap in clinical studies and randomized trials analyzing adverse cardiovascular effects of e-cigarette use, the existing literature supports that different constituents of e-cigarettes such as nicotine, carbonyls, and particulate matters carry potential risk for cardiovascular diseases (CVD) on its users.
